[C] Under-Voltage Protection (P-side, UVDB)

a1. Control supply voltage rises : After the voltage level reachs UVDBr, the circuits start to operate when the next input is applied.

a2. Normal operation : IGBT ON and carrying current.

a3. Under voltage trip (UVDBt).

a4. IGBT OFF in spite of control input condition, but there is no FO signal output.

a5. Under-voltage reset (UVDBr).

a6. Normal operation : IGBT ON and carrying current.

Note : RC coupling at each input (parts shown dotted) may change depending on the

PWM control scheme used in the application and on the wiring impedances of

the application’s printed circuit board.
